Embodiment 1

[0034] figure 1 It is a schematic diagram of the structure of the electronic cam control system of the present invention, such as figure 1 As shown, this embodiment provides an electronic cam control system, the electronic cam control system is used in a filling line, the filling line includes a conveyor belt and a filling station, the conveyor belt carries the packaging to be filled, the After the moving speed of the filling station is synchronized with the moving speed of the conveyor belt, the filling station fills the package to be filled with liquid. The electronic cam control system includes an input unit 11, a control unit 12, and a first driver 13 and the second driver 14, wherein: the input unit 11 sends the control parameter to the control unit 12; the control unit 12 controls the movement of the first driver 13 according to the control parameter, and the control unit 12 controls the movement of the first driver 13 according to the The movement of the second driver ...

Embodiment 2

[0039] figure 2 It is a schematic diagram of the structure of the electronic cam control system of the present invention, such as figure 2As shown, in the electronic cam control system provided in this embodiment, the electronic cam control system includes an input unit 21, a control unit 22, a first driver 23 and a second driver 24. The difference from the previous embodiment is that the The first driver 23 includes a first motor and a first shaft 232, wherein: the first motor is a servo motor 231; through the virtual main shaft function of the servo motor 231, no encoder needs to be installed, so that the second shaft is opposite to the first shaft The position is absolutely synchronized, thereby avoiding the accuracy error caused by the encoder. Regardless of high speed, low speed, acceleration and deceleration, the first axis and the second axis run reliably synchronously, and all control axes are linked to ensure absolute synchronization of control commands, avoiding c...

Embodiment 3

[0043] The present invention also provides an electronic cam control method, the electronic cam control method comprising:

[0044] Inputting control parameters to the control unit through the input unit;

[0045] The control unit calculates the motion parameters of the first driver according to the control parameters, and calculates the motion parameters of the second driver through the motion parameters of the first driver;

[0046] The first driver performs linear motion for driving the conveyor belt;

[0047] The second driver makes a linear motion and is used to drive the filling station.

[0048] Combined with the above electrical structure and electronic cam tracking curve, the specific control process is as follows:

[0049] First, calculate the electronic cam curve and the speed multiplier of the master and slave axes according to the mechanical parameters, encoder resolution and the number of filled bottles to ensure that the speed of the master and slave axes is t...

Abstract

The invention provides an electronic cam control system and a control method. The electronic cam control system is intended for filling an assembly line and includes an input unit, a control unit, a first driver and a second driver. The input unit transmits control parameters to the control unit. The control unit moves the first driver based on the control parameters. The control unit moves the second drive based on the move of the first driver. The first driver and the second driver move linearly. According to the method, the control unit moves the second driver based on the move of the first driver, replaces traditional mechanical cams with electronic motion-controlled cams, thus simplifying the manufacturing, installation, operation and maintenance of devices and reducing mechanical breakdown. The electronic cam control system uses the characteristics of electronic cams to set production scale of choice and obviates the need for the exchanging of mechanical apparatuses.

Description

technical field [0001] The invention relates to the technical field of electromechanical integration, in particular to an electronic cam control system and a control method. Background technique [0002] Bottled liquid products are often used in daily life, such as potions, liquid beverages, etc., which are all filling control products involved in the filling line and belong to the packaging field. [0003] In the past, the filling production line used mechanical cams to realize filling, followed the shaft to drive the filling station, and followed the speed of the conveying spindle, that is, the conveyor belt for filling. After a long time of operation, the mechanical cam will wear out, causing the filling position to shift. Difficult to repair and replace mechanical cams. In addition, there is also a control method using ordinary PLC on the market, but this method is affected by the timing of the program and cannot achieve accurate synchronization at high speeds. [000...
